Summary: Not all bad
Comment: Contrary to what many may say, this really isn't a bad product. I've used it for years and have found it quick, reliable and easy-to-use. Our company used CVS (mostly because it's free and it has the basic necessities) but the database was corrupted and the check-in/check-out process wasn't as intuitive. In 7 years, I've never had a VSS database fail me.
I agree that VSS hasn't had any major innovations in a VERY long time... Some reports would be greatly appreciated as well as the ability to see exactly what the differences are between two MS Word docs or Excel spreadsheets (they're Microsoft products too for goodness sake!) but overall it's a decent tool.

Summary: do not under any circumstances use this product
Comment: Source Code Management, no doubt, is a vital part of any development shop. Any team based development effort needs a centralized repository in which to store their work.That being said, I would implore you to choose another product - such as the open source CVS (which can hook into VS.net with the right plug-ins).
VSS is a buggy, unreliable, unbearably slow...and fundamentally unuseable product. This is *not* the sort of system you should use hold vital data that ammounts to months and months of hard work.
For your sanity and your time, DO NOT buy this product. As each version seems to bring very little in the way of rethinking this disaster, Microsoft has made it very clear that they could care less about source control.
(by the way, MS doesn't even use this product in-house).
